I have a Debian server which creates PDF thanks to wkhtmltopdf, and I would like to write with urdu font in this PDF.There are few packages that can handle installation of these fonts (fonts-nafees, fonts-paktype, ...), but I have characters that can't be displayed.I tried to install manually other .ttf files (in /usr/local/share/fonts) (http://www.urdujahan.com/font.html) : no more results, still the same missing characters.

The missing characters are : - ہ - ے

If somebody knows why I can't display these characters, and how to fix that...
